Today the United States Federal Trade Commission issued a report in which it detailed a number of consumer-focused issues arising from the growing Internet of Things (IoT). Companies should pay attention to the portion of the report containing the Commission’s recommendations on best practices to participants (such as device manufacturers and service providers) in the IoT space.

The Commission structured its recommendations around four of the “FIPPs” – the Fair Information Practice Principles – which first appeared in the 1970s and which inform much of the world’s regulation geared to protect personal data. The recommendations focused on data security, data minimization, notice and choice.

DATA SECURITY

IoT participants should implement reasonable data security. The Commission noted that “[o]f course, what constitutes reasonable security for a given device will depend on a number of factors, including the amount and sensitivity of data collected and the costs of remedying the security vulnerabilities.” Nonetheless, companies should:

Implement “security by design”

Ensure their personnel practices promote good security

Retain and oversee service providers that provide reasonable security

Implement “defense-in-depth” approach where appropriate

Implement reasonable access control measures

Monitor products in the marketplace and patch vulnerabilities

Security by Design

Companies should implement “security by design” into their devices at the outset, rather than as an afterthought by:

Conducting a privacy or security risk assessment to consider the risks presented by the collection and retention of consumer information.

Incorporating the use of “smart defaults” such as requiring consumers to change default passwords during the set-up process.

Considering how to minimize the data collected and retained.

Testing security measures before launching products.

Personnel Practices and Good Security

Companies should ensure their personnel practices promote good security by making security an executive-level concern and training employees about good security practices. A company should not assume that the ability to write code is equivalent to an understanding of the security of an embedded device.

Retain and Oversee Service Providers That Provide Reasonable Security

The Commission urged IoT participants to retain service providers that are capable of maintaining reasonable security and to oversee those companies’ performance to ensure that they do so. On this point, the Commission specifically noted that failure to do so could result in FTC law enforcement action. It pointed to a recent (non IoT) case in which a medical transcription company outsourced its services to independent typists in India who stored their notes in clear text on an unsecured server. Patients in the U.S. were shocked to find their confidential medical information showing up in web searches.

The “Defense-in-Depth” Approach

The Commission urged companies to take additional steps to protect particularly sensitive information (e.g., health information). For example, instead of relying on the user to ensure that data passing over his or her local wireless network is encrypted using the Wi-Fi password, companies should undertake additional efforts to ensure that data is not publicly available.

Reasonable Access Control Measures

While tools such as strong authentication could be used to permit or restrict IoT devices from interacting with other devices or systems, the Commission noted companies should ensure that they do not unduly impede the usability of the device.

Monitoring of Products and Patching of Vulnerabilities

Companies may reasonably decide to limit the time during which they provide security updates and software patches, but must weigh these decisions carefully. IoT participants should also be forthright in their representations about providing ongoing security updates and software patches to consumers. Disclosing the length of time companies plan to support and release software updates for a given product line will help consumers better understand the safe “expiration dates” for their commodity internet-connected devices.

DATA MINIMIZATION

Data minimization refers to the concept that companies should limit the data they collect and retain, and dispose of it once they no longer need it. The Commission acknowledged the concern that requiring data minimization might curtail innovative uses of data. A new enterprise may not be able to reasonably foresee the types of uses it may have for information gathered in the course of providing a connected device or operating a service in conjunction with connected devices. Despite certain concerns against data minimization, the Commission recommended that companies should consider reasonably limiting their collection and retention of consumer data.

The Commission observed how data minimization mitigates risk in two ways. First, the less information in a database, the less attractive the database is as a target for hackers. Second, having less data reduces the risk that the company providing the device or service will use the information in a way that the consumer does not expect.

The Commission provided a useful example of how data minimization might work in practice. It discussed a hypothetical startup that develops a wearable device, such as a patch, that can assess a consumer’s skin condition. The device does not need to collect precise geolocation information in order to work, but it has that capability. The device manufacturer believes that such information could be useful for a future product feature that would enable users to find treatment options in their area. The Commission observed that as part of a data minimization exercise, the company should consider whether it should wait to collect geolocation information until after it begins to offer the new product feature, at which time it could disclose the new collection and seek consent. The company should also consider whether it could offer the same feature while collecting less information, such as by collecting zip code rather than precise geolocation. If the company does decide it needs the precise geolocation information, the Commission would recommend that the company provide a prominent disclosure about its collection and use of this information, and obtain consumers’ affirmative express consent. And the company should establish reasonable retention limits for the data it does collect.

As an aspect of data minimization, the Commission also discussed de-identification as a “viable option in some contexts” to help minimize data and the risk of potential consumer harm. But as with any conversation about de-identification, the Commission addressed the risks associated with the chances of re-identification. On this note, the Commission referred to its 2012 Privacy Report in which it said that companies should:

take reasonable steps to de-identify the data, including by keeping up with technological developments;

publicly commit not to re-identify the data; and

have enforceable contracts in place with any third parties with whom they share the data, requiring the third parties to commit not to re-identify the data.

This approach ensures that if the data is not reasonably de-identified and then is re-identified
in the future, regulators can hold the company responsible.

NOTICE AND CHOICE

Giving consumers notice that information is being collected, and the ability to make choices as to that collection is problematic in many IoT contexts. Data is collected continuously, by many integrated devices and systems, and getting a consumer’s consent in each context might discourage use of the technology. Moreover, often there is no easy user interface through which to provide notice and offer choice.

With these concerns in mind, the Commission noted that “not every data collection requires choice.” As an alternative, the Commission acknowledged the efficacy of a use-based approach. Companies should not be compelled, for example, to provide choice before collecting and using consumer data for practices that are consistent with the context of a transaction or the company’s relationship with a consumer. By way of example, the Commission discussed a hypothetical purchaser of a “smart oven”. The company could use temperature data to recommend another of the company’s kitchen products. The consumer would expect that. But a consumer would not expect the company to disclose information to a data broker or an ad network without having been given notice of that sharing and the ability to choose whether it should occur.

Given the practical difficulty of notice and choice on the IoT, the Commission acknowledged there is no one-size-fits all approach. But it did suggest a number of mechanisms for communications of this sort, including:

The Commission’s report does not have the force of law, but is useful in a couple of ways. From a practical standpoint, it serves as a guide for how to avoid engaging in flagrant privacy and security abuses on the IoT. But it also serves to frame a larger discussion about how providers of goods and services can and should approach the innovation process for the development of the Internet of Things.
